It is easy to use a THC pen. They are mostly draw or button-activated. Draw on the mouthpiece (or inhale while pressing the button) to engage the heating coil which vaporizes the concentrate. Some, such as THC Vape from Killa Kush, are pre-filled and pre-charged and can be used right away. Take small puffs first to assess effects. They are designed for ease of use with battery, filter, and pre-filled cartridge for a continuous experience.
